In addition, the machine shall be designed according to the principles of EN ISO 12100:2010 for relevant but not significant hazards, which are not dealt with by this document. 5.2 Controls 5.2.1 Safety and reliability of control systems For the purpose of this document, safety-related part of a control system means the system which implements safety functions from the initial device, e.g. actuator, position detector or sensor up to and including the power control element of the final machine actuator, e.g. motor or brake. Safety-related parts of the control system of this machine comprise parts concerning the following functions and they shall fulfil the requirements of the PL given below in accordance with the requirements of EN ISO 13849-1:2008:
for starting: PL = c (see 5.2.3);
for normal stop: PL = b (see 5.2.4);
for emergency stop: PL = c (see 5.2.5);
for operational stop: PL = c (see 5.2.6);
for standstill monitoring: PL = c (see 5.2.6 and 5.2.8);
for interlocking: PL = c (see 5.2.6 and 5.2.7);
for mode selection: PL = c (see 5.2.7). Verification: By checking the relevant drawings and/or circuit diagrams, calculation and inspection of the machine SIST EN 15571:2015
EN 15571:2014 (E) 17 5.2.2 Position of controls The main control devices, i.e. devices for starting, operational/normal stop, emergency stop, mode selection, shall be located at the operator's position adjacent to the control display (at the main control panel) at a distance of at least 1 200 mm and not exceeding 1 800 mm from the floor level. The main interrupter control shall be located on the main electrical board. Any safeguarding equipment reset control device shall be located outside the protected zone and shall not be reachable from inside the protected zone. The emergency stop device shall be provided at each working station (see 6.3) and in particular: a) at the main control panel; b) at the mobile control panel, connected by cable or wireless system (if provided); c) adjacent to all hold-to-run control; d) adjacent to all limited movement control; e) at a distance of maximum 1 500 mm for front to the workpiece loading and unloading area; f) inside any peripheral enclosure fitted with access door (see 5.3.4). Verification: By checking the relevant drawings and/or circuit diagrams, inspection of the machine and functional testing of the machine. 5.2.3 Starting For starting or restarting, the starting function of each head machining shall be at least PL = c, in accordance with the requirements of EN ISO 13849-1:2008. The beginning of the piece working cycle (cycle start) shall be possible only when all safeguards described in 5.3.4 are in
